I drink also. I go outside and smoke a cigarette (I live in a small village, even if it’s a stranger I talk to, which actually I think I prefer strangers, my loneliness is cured, at least for that moment) and someone is always bound to say something.
I think you should go out with some friends, or family, or outside of being with your boyfriend think about and then involve yourself in things that you like to do or have a passion for. If you let yourself sink further than you are now..it won’t be pretty. But I think you will be just fine without anti-depressants.
